How to use the Contacts Merger — 4 steps

  1. 1

    Export contacts from each phone or account as a .vcf file (see the guide below), then drop the files onto the box.

  2. 2

    Nothing to set — duplicates are matched by name, phone and email automatically.

  3. 3

    Press 🔀 Merge contacts. Everything runs inside your browser — nothing is uploaded.

  4. 4

    Press ⬇️ Download merged .vcf and import it into Google Contacts, iPhone or Outlook.

💡 Tip: Keep the download — it doubles as a full backup of your contacts.

Every phone switch leaves a contact mess

An old Android backup, an iPhone export, the Gmail contacts that synced sometimes — most people's contacts live in three overlapping copies, with the same person appearing twice with different numbers. This tool cleans it up: drop in all your .vcf files, and contacts are merged by matching names, phone numbers and emails. Two entries for the same person become one card carrying every number and address from both.

How to export your contacts first

  • iPhone: iCloud.com → Contacts → select all → Export vCard.
  • Android: Contacts app → Fix & manage → Export to file.
  • Gmail: contacts.google.com → Export → vCard.
  • Outlook: People → Manage → Export contacts.

Then import the merged file back the same way — one clean list everywhere. Because everything runs in your browser, your contact list (names, numbers, emails, addresses) is never uploaded to us or anyone.

How to merge contacts on iPhone, Android and Google Contacts

Phones do not give you a real merge — they hide duplicates, which is not the same thing. Exporting to a .vcf file and merging it properly takes about two minutes and leaves you with one clean file you can import anywhere.

  1. iPhone. Open Settings → [your name] → iCloud → Contacts and make sure it is on, then go to iCloud.com → Contacts on any computer, press Ctrl/Cmd + A to select everyone, and choose Export vCard from the settings menu. That file is your iPhone contacts.
  2. Android / Google Contacts. Go to contacts.google.com → Export, choose vCard (for iOS Contacts) and download.
  3. Outlook. File → Open & Export → Import/Export → Export to a file → Comma Separated Values, then convert with our CSV merger — or export individual contacts as vCards.
  4. Merge them here. Drop every .vcf file into the box above. Contacts with the same name and number are combined into one card, and duplicate phone numbers and emails inside a single card are removed too.
  5. Import the result. On iPhone, email the merged .vcf to yourself and open the attachment. On Android, use contacts.google.com → Import.

Nothing is uploaded at any point — the merge runs inside your browser, which matters more for a contact list than for almost any other file you own.

Frequently asked questions

How do I merge two VCF contact files into one?

Export contacts from each phone or account as .vcf, drop the files into the tool above, and click Merge. Duplicates are combined automatically and you download one clean .vcf ready to import anywhere.

How are duplicate contacts detected?

Contacts are matched by name, phone number and email — if two cards share any of these, they're merged into one card that keeps every unique number, email and address from both.

Will this work with iPhone and Android exports together?

Yes — vCard is the universal contacts format. You can mix exports from iCloud, Android, Gmail and Outlook in one merge.

Is it safe to use with my real contact list?

Yes — the merge runs entirely in your browser. Your contacts are never uploaded, transmitted or seen by anyone, including us.

How do I merge duplicate contacts on iPhone?

Export your contacts from iCloud.com as a vCard, drop the file into the merger above, and import the cleaned file back. iPhone’s own “Link Contacts” only hides duplicates on that device; this actually combines them into one card.

Can I merge contacts from an iPhone and an Android phone?

Yes. Export a .vcf from each — iCloud.com for the iPhone, contacts.google.com for the Android — and drop both files in. Cards for the same person are combined rather than duplicated.
